COA | Unit-2 | Lecture-22 | Logical Operations | AKTU B.Tech Computer Science

Описание: Welcome to CS Pathshala! 🎓

In this video, we explain the concept of Logical Operations — essential operations performed by the ALU to manipulate data at the bit level in digital computers.

You’ll learn how basic logical operations like AND, OR, NOT, XOR, XNOR, NAND, and NOR work, how truth tables are formed, and how these operations are used in arithmetic processing, decision making, masking, bit testing, and control instructions.
We also discuss how logical operations are implemented in hardware using logic gates, and how they appear in assembly instructions across different architectures.

With clear examples and step-by-step bitwise calculations, this lecture will help you understand how logical operations transform binary data and why they are crucial for programming, circuit design, and processor functioning.

This topic is part of Unit 2 – Arithmetic and logic unit as per the AKTU syllabus, and is important for GATE and NET Computer Science preparation.

📚 Stay tuned for more concept-based lectures on COA, OS, DBMS, DS, TAFL, Java, and Python.
